The device .for moving freight cars and the like along railroad tracksas. embodied in Figures 1, 2, 3 and 4 comprises a main frame F which maybe-produced as. one integral unitor may be com- 2, Claims. (Cl. 105-141)posed of: several structural parts It has two longitudinal side walls i0and-ll respectively; extending parallel to each other. .The forward endportions I2 and 13 respectively of said side walls extend outwardlyat-an angle of approximately 60 degrees to each other and-upwardlyatan:0-btuse angle to the. main portion of the side walls. On the" forwardend of each forward side wall portion. 12 and i3 afront wall'l4w'andl5,lrespectively, isv formed and. extends inwardly from thecorresponding side wall portion at a right angle thereto. Between theinner edges of the twofront walls f4 and it. an opening. is left, whichis large enough to permit a portion of a railroad car wheel H5 to.enter.

on the inner end of eaohforward side wall portion [2: and l'3an.intermediate wall I! and l8respectively is. formed'and extends inwardlyfrom and at a right angle :to the adjacent forward side waitportionand'parallel to. the. front. wall H or 5. The intermediate wallsare permanently'comnected with each other in the vertical longitudinalcenter plane of the main frame F.

Substantially Z-shaped brackets 119 and 20' respect'ivel y are securedto the inside face and adjacent to the rear end of the side walls 10 andH respectively'so that the webs 21 and 22 respectively of said bracketsextend toward each other and that'the inner flanges 23 and 24 of saidbrackets are spaced fromv eachother and extend downward-1y parallel toeach other. An axle 25 extends between thefiange23 and 24 and isrotatably'supported by them. On the central portion of the axle 25 asmall roller 26. is rigidly mounted and is provided with annularendflanges 21.

A'reinforcing bar 238' is. welded or otherwise secured atiits rear endportion to the undersides of the side wall In and the intermediate wallI! and extends forwardly, outwardly and upwardly therefrom. The forwardend portion of said bar is welded or otherwise fastened on the undersideof the front wall H. A similar reinforcingbar 2:9. is secured at itsrear end portion to the under-- sides of the side wall I l and theintermediate wall I58 at itsfron-t end portion to the underside of thefront wall ['5 A bracket 39"has an upper flange 31' with whic it is:weldedor otherwise secured to the inside surface of the reinforcing bar28 intermediate the ends thereof. From the upper flange 3la web 32extends downwardly and inwardly and on the lower end of the web 32 adownwardly extending lower flange '33 is formed. A similarly shaped.second bracket 34 is secured with its upper flange 35 'to the insidesurface of the reinforcingbar' 3 29 oppositely from the bracket 36. Aweb 36 extends downwardly and inwardly from the upper flange and a lowerflange 31 projects downwardly from said web 36.

A shaft 38 extends through and is rotatably supported by the two lowerflanges 33 and 31, and projects laterally beyond one of the side walls,for instance the side wall I6.

A roller 39 is rigidly mounted on the shaft 38 between the lower flanges33 and 31. The roller has a cylindrical middle portion 40 from whichconical flanges M and 42 respectively extend. On

the circumferential surfaces of the two flanges" are providedlongitudinally running sharp projections or teeth 43 and 44 respectivelywhich are adapted to engage the head of a track rail 45.

The small roller 26 rests rotatably onthehead of the rail 45 and therelative dimensions of said small roller and of the roller 39 are such48 between the front wall I5 and the intermediate On therear endportions of the shafts 46 and 48'respecti'vely meshing bevel gears 58and 5| respectively are rigidly mounted and are located ad- J'acent tothe rear surfaces of the intermediate walls-l1 and I8 respectively. Adrive shaft 52 extends transversely through the main frame F and isrotatably supported in the side walls I 0 and II of the frame rearwardlyof and adjacent to the bevel gears 59 and 5|. Two bevel gears 53' and 54respectively are rigidly mounted on the drive shaft 52 and are arrangedadjacent to the inner faces of the side walls I0 and I I respectively.The bevel gears 53 and 54 mesh with the bevel gears and 5| respectively.

On the end portion of the drive shaft 52 projecting beyond the side wallID a sprocket gear 55 is rigidly mounted and a sprocket gear 56 isrigidly mounted on the end portion of the shaft 38 projecting beyond theside wall Ill. A sprocket chain 51 is trained over the two sprocketgears.

On the end portion of the drive shaft 52 projecting beyond the frameside wall I I a comparatively large spur gear 58 is rigidly mounted anda large gear housing 59 is arranged on and secured to the'mainframe Fabove the drive shaft 52.-

Rearwardly of the gear housing a base plate 59 is secured to the topedges of the side walls I0 and I land a motor 60 is mounted onsaidplate. Preferably this motor is a one and one half horse power internalcombustion engine driving the reduction gear transmission contained inthe gear housing."

This gear transmission comprises and drives a transverse shaft 6|extending outside of the gear housing. A comparatively small spur gear62 is rigidly mounted on the end portion of said driven shaft projectingoutside of the housing and meshes with the spur gear 58.

On the under edge of each side wall I0 and I I a bearing 63 is securedapproximately half way between the rear axle 25 and the transeverseshaft 36. A transverse axle 64 is journaled in said bearings andtwo-rubber tired wheels 65 are 4 mounted on said axle. The radius ofsaid wheels is of such length that the device is adapted to ride on therubber tired wheels and the small roller 26 and the roller 39 arearranged above the ground, when the device is removed from the rail 45but that the tires of the wheels 65 do not touch the ground, when theroller 26 and the roller 39 rest on said rail. v An upwardly andrearwardlyextending handle bar. 66 is secured to the rear portion pf themain frame F facilitating manual moving of the device.

When the device is to be used to move a railroad car, it is placed on atrack so that the small wheel 26 and the roller 39 rest on the head ofthe rail 45. The motor 60 is started driving the roller 39 by means ofthe spur gears 62 and 58,

.the transverse shaft 52, the sprocket gear 55.

sprocket chain 57, sprocket gear 56 and shaft 38. The wheel I6 of therailroad car enters between the corrugated rollers and is engaged andset into rolling motion by them, since said rollers are rotated bythemotor 60; In Figures 5, 6 and 7 a modified form of the car movingdevice in accordance to the present invention is illustrated and thedevice as embodied in said figures comprises a main frameMrcomprisingtwo longitudinal side walls 61 .and 68 respectivelyand a base plate 6 9secured to the top edges of the sidewalls and holding them in positionso that they are spaced from each other and run parallel to each other.Adjacent to each end of each side wall a bracket 16 is located. Eachbracket Ill has upwardly extending upper flange II, a web "extending atan angle from the lower edge'of. the flange II and a lower flange I3extending downwardly from the web parallel to the upper flange'II. V

'Ahandle bar I4 is secured to one end portion, hereinafter called therear end portion, of one of the side walls, for instance the side wall68, so that it extends rearwardly and upwardly from said wall. A rearaxle I5 is rotatably supported by the-lower flanges 13 of the rearbrackets I0 and extends beyond one of the side walls, for instance theside wall 68. A front axleI6 is rotatably supported in the lower flangesI3 of the forwardbrackets I6 and extends beyond the'same side wall asthe rear axle I5. The two axles are arranged so that their axes arelocated at the same level below the under edge of the side walls 61 and68 and so that they run parallel to each other. 7

On each of the axles I5 and I6 a roller I8 is rigidly mounted having acylindrical middle portion 19 and outwardly flaring conical end portionsor flanges 86 provided on their circumferential surfaces withlongitudinal sharp projections or teeth 8| adapted to engage the head ofa track rail 82 on which the device is placed. The rollers I8 arelocated between the oppositely arranged brackets I6 and approximately onthe longitudinal center of the main frame M. On the end portion of thefront axle I8 projecting beyondthe side wall 68 and on the correspondingend portion of the rear axle I5 a sprocket gear 83 is rigidly mounted.

A gear housing 84 is mounted on the base plate 69 adjacent to the sidewall 68 and contains a reducing gear transmission (not shown) adapted tobe driven by a motor 85 indicated in broken lines in Figure 5. Atransverse shaft 86 forms a part of the not shown transmission andextends outwardly of the housing 84 beyond the side wall outside endportion of the shaft 86 and a sprocket chain 88 is trained over thesprocket gears 83 and 81 so that the rollers 18 are rotated when themotor 85 is started.

A brace bar 89 is secured to the inside surface of each side wall 61 and'68 just in front of the base plate 69 and extends upwardly andforwardly and at an acute angle to the adjacent side wall. A stub shaft90 is secured to the brace bar 89 adjacent to the side wall 68intermediate the ends of said brace bar and extends outwardly therefrom.Two sprocket gears 9i and 92 are rotatably mounted on the stub shaft 90so that the outer gear 92 of the outer sprocket gear 92 is in engagementwith the sprocket chain 89.

A shaft 93 extends between and is rotatably supported by the two bracebars 89 and one end portion of said shaft extends laterally beyond thebrace bar adjacent to the side wall 68. A sprocket gear 94 is rigidlymounted on said end portion of the shaft 93 and a sprocket chain 95 istrained over the inner gear 92 and the sprocket gear 94.

A roller 91 is rigidly mounted on the portion of the shaft 93 locateddirectly above the rail 82 when the device is placed on said rail. Theroller 91 has a cylindrical middle portion 98 from which two conicaloutwardly flaring end portions or flanges 99 and I09 extend.Longitudinal sharp projections l9! are provided on the circumferentialsurface of the conical flange 99 and similar projections I02 arearranged on the conical flange I00.

When a railroad car (not shown) is to be moved the device is placed onthe rail 82 and is pushed forwardly until the projections on the roller98 engage the wheel 103 of the railroad car. Since the flange I04 ofsaid wheel comes nearer to the roller 91 than the outer edge of thetread I05 the conical flange 99 of the roller engaging the wheel flangeI04 is smaller than the conical flange I00 engaging the wheel tread. Themotor is started and the rollers 19 are rotated in clockwise direction.The two sprocket gears 9| and 92 and the roller 91, are rotated incounter-clockwise direction so that the roller 91 exerts an upward pullon the wheel I93 rotating it in clockwise forward direction.

From the foregoing description it is thought to be obvious that a devicefor moving freight cars constructed in accordance with my invention isparticularly well adapted for use by reason of the convenience andfacility with which it may be assembled and operated.

I claim:
